SAWING AND FILING MACHINE.

a county of Essex and State of New Jersey,

both citizens 'of the United States, have invented certain Improvements in Sawing and Filing Machines, of which the following is a specification.

The objects of this invention are to provide a machine of this character which shall be compact and have the countershaft for driving it mounted upon the same base; toprovi'de a long bearing for said countershaft, which is really the crank-shaft, and to enable the loose pulley to have another bearing than on'said shaft; to secure a movement of the saw or file whlch shall be simple and yet provide a slow working stroke and a quick return or idle 'str oke; to provide bearings which shall be dust proof and protected from filings or sawdust; to secure a simple adjustment of the work table to support the saw or file at its upper end in an improved mannerQan-d to obtain other advantagesand' results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several figures, Figure-1' is an elevation ofthe machine from its side which is at'the right hand of the operator; Fig. 2 is a central vertical section, lookingin the same direction as in F ig; 1; Fig. 3 is 'a detail section online A-'A of Fig. 2, looking in'the directionindicated by the arrow; Fig. 4 is a central vertical section at right angles to the one shown in Fig. 2. 1

Our improved machine is adapted both for sawing and for filing, and although'in the drawings we havesh'own a saw mounted in the machine, it will be'understood that the saw could be removed and a file inserted without affecting the invention.

In said drawings, 1 indicates the broad flaring base of the body'por'tion 2 of'the machine, said base being adapted to be bolted to the floor or other foundation and supporting a hollow boX-likestandard 3 having'central vertical bearings't and 5 at its top and bottom, respectively, for'the reeiprocating plunger '6 which carries the saw 7. Thisplunger' has areduced upper Specification of Letters Patent.

end 8 which is centrally and axially socketed to receive the saw 7 or other tool and also cut away at one side to expose the shank of the tool in said socket. A collar '9 slips over said reduced end, and a set screw 10 workingthrough one' side of said collar is adapt- Y ed to clanrp the tool in place, said set screw worklng through a thickened side of the collar for greater'strength. The bearing 4 exlug- 14; Inthis bearing is mounted an auxiliary tool' holder 15, 'slidable therein, and having at its lower end a socket 16 for the top of the tool and a set screw 17 working through the wall-of said socket to-clamp the EW JERSEY;

upper end of the tool, as shown ih-"Fig'. 4;

moreesp'ecially. The auxiliary tool holder 15 has at its upperendta head 18, and'between said head and the bracket 13 is a 23 whiclrare bolted to the body portion 2 and extend upward therefrom on opposite sides of saidbody'port'ion as viewed by' the operator. One or these arms has 'front and rear branches 27', 27 near its top,in which are pivoted thumb-screws 28, so that by loosening one of said screws and tightening the other the table may be swung onits trun- 1110118 to secure desired angular ad uStment. The trunn'1ons22 are shown'in' F1g.'1 as made fast'with respect-to the table 21 by means of setscrews29." I

Therreciprocating tool holder 6 is received intermediate of its bearings'A: and 5 by the forked end of'a horizontally disposed 'levershaft' 30, see*Fig.-"2 ,-and a pin -31 is passed through" said forked end and tool holder. The said lever shaft extends rearward from the operator, first through a bushing or sleeve 32 which is fast with respect to a second sleeve or bushing 33 disposed at right angles to the first mentioned one and which receives a stud 3% projectlng horizontally from a fixed portion of the machine, so that the lever shaft 30 may rock thereon as a fulcrum. It will be understood that the stud 3% lies below the lever shaft 30, and that said lever shaft is slidable in its sleeve or bushing 32 of said fulcrumal mounting. Farther out from the body portion 2 ofthe machine, the lever shaft 30 ex tends slidably through a sleeve or bushing 35 which has an upwardly extending lateral portion 36 bored at right angles to the sleeve or bushing 35 to receive the crank pin 37 of a crank disk 38, said crank disk being disposed in a vertical plane parallel to the lever shaft 30, and at the left hand side of the same from the operators standpoint, as shown in the drawing.

A heavy rigid hanger 39 is bolted to the base 1 of the machine and extends upwardly therefrom and away from the operator to provide a bearing 40 for the crank shaft 41, said hanger also affording a support for the stud 34; upon which the fulcrumal mounting is pivoted. The said bearing 40 is reduced at its ends away from the crank disk, as at 42, to receive the idle pulley 43, and adj acent to said idle pulley the driving pulley 44 is fixed on the crank shaft 41, all as clearly shown in Fig. 3. A belt shifter l-5is pivoted upon the said hanger 39, said belt shifter, the belt (not shown) and pulleys therefor being all'disposed at the lefthand side of the machine, from the operators standpoint, out of the way of the bracket 13.

A sheet metal shield 46 is preferably arranged above the lever shaft 30, said shield being supported by ears 47 and L8 bolted or screwed to the body portion 1 and bearing 40, respectively. It will be noted that by reason of this shield and the cap 12 over the upper end of the tool holder bearings, filings or sawdust from the work cannot find access to the bearings of the machine to damage the same. Preferably, a transversly slitted socket piece 49 is inserted in the tool holder when a saw is used in the machine, as shown in the drawings, this socket piece being removed when a file is put in, if desired. The upper bearing 4 for the tool holder is preferably babbitted, as shown at 50, the babbitt being readily poured into the bearing when the work table is removed.

In operation, the driving pulley 4a is 1'0- tated in the direction shown by the arrow on the drawing, thus causing the crank pin 37 to revolve and the sleeve 35 to move in a circular path in the plane of the lever shaft 30. In order-to permit this movement, the

said sleeve of course slides on the lever shaft, but the up and down movement of the sleeve imparts to the lever shaft 30 a rocking motion upon the fulcrumal stud which causes the tool holder to move up and down. Obviously, since the lever shaft is pivoted to the tool holder, up and down movement of the latter will cause a slight longitudinal movement of the lever shaft in its fulcrum sleeve 33, and also in the crank sleeve 35. It will be noted, further, that as the crank pin 37 is in a horizontal plane through the crank shaft and center of the crank disk, the position of the crank sleeve varies considerably with respect to the fulcrumal sleeve according to whether said crank pin is at the side of said center next to the tool holder or at the side away from said tool holder. When the crank pin is at the side of the center next to the tool holder, obviously the arm of the lever shaft from said crank pin to the stud 34; is short and the movement of the tool holder is correspondingly rapid. On the other hand, when the crank pin is at the side of the center of the crank disk away from the tool holder, the arm of the lever shaft between said crank pin and the fulcrum stud 3a is long and the movement of the tool holder is correspondingly slower. I therefore rotate the crank pin in the direction shown in the drawing, that is to say, so that the crank pin will move upward at the side of the center of the crank disk awayfrom the tool holder and move downward between said center the tool holder, whereby the up stroke of the tool holder, which is the idle stroke or return stroke of the tool, will be quick, and the downstroke of the tool holder, which is the working or cutting stroke, will be slower. Obviously, this could be reversed or the upstroke be made slowly and the downstroke quicker, if desired, and also by varying the position of the fulcrumal stud 3 t or changing the diameter of the crank disk, modifications of the variations of speed of the stroke can be obtained, as will be understood by skilled mechanics.

The auxiliary or upper tool holder 15 not only guides the tool and holds it against lateral deflection, but also by virtue of the spring 19 it always pulls upward on the tool so as to hold a flexible tool, like the saw shown, taut and straight.

Having thus described the invention, what we claim is 1. In a machine of the character described, the combination of a hollow stand ard having spaced apart vertical bearings at its top and bottom, a tool holder extending between said bearings and protruding from the top one, means attached intermediate the ends of said tool holder and projecting laterally through a side of the stand ard for reciprocating said tool holder, arms extending upward from said standard'on opposite sides of said tool holder, a work table hinged to said arms upon a horizontal axis intersecting the axial central line of the tool holder, and set screws on opposite sides of said line of hinging for adjusting said table.

2. In a machine of the character described, the combination of a hollow standard having spaced apart vertical bearings at its top and bottom, the bottom one being inclosed and projecting upwardly within the standard and the top one being of less diameter than the standard and extending upwardly above the same, a tool holder in said bearings projecting at its upper end above the top one, a cap on said upper end of the tool holder of less diameter than the standard and depending over said upper bearing, tool holding means on said tool holder above said cap, table supporting arms extending upwardly from said standard free from said "tool supporting means and cap, and a table above all of said parts apertured in alinement with the tool holder.

3. In a machine of the character described, the combination of a hollow standard having spaced apart vertical bearings at its top and bottom, the bottom one being inclosed and projecting upwardly within the standard and the top one being of less diameter than the standard and extending upwardly above the same, a tool holder in said bearings projecting at its upper end above the top one, and having a tool socket thereat, a cap on said upper end of the tool holder of less diameter than the standard and depending over said upper bearing, a collar on said reduced end above said cap, a set screw for clamping said collar on said reduced end and holding both a tool and said collar in place, and means attached intermediate the ends of said tool holder and projecting laterally through a side of the standard for reciprocating the tool holder.
